you can also try to edit

$ mcedit thirdparty/ffmpeg-4.4/libavcodec/libx265.c

and just add this line

 ....
    ctx->params->logLevel = X265_LOG_NONE;

just before
    ctx->encoder = ctx->api->encoder_open(ctx->params);

it compiles but I currently can't test it - termux is rolling distro and
right now xfwm4 apparently broken..
